Promotion effects on the synthesis of higher alcohols. Seventh quarterly report, March 1984-May 1984
During the seventh quarter, a study of CO hydrogenation over alkali-promoted Rh/La/sub 2/O/sub 3/ catalysts was carried out by addition of ethylene to clarify the alkali promotion effect on the specific reactions in this synthesis. Conclusions of this study are: the effect of alkali promotion on the activity and selectivity for CO hydrogenation over Rh/La/sub 2/O/sub 3/ is dependent upon the type of alkali promoter; and the effect of alkali promotion on La/sub 2/O/sub 3/ can be summarized as follows: (1) Li-promotion enhances the rate of formation and selectivity of C/sub 2/ oxygenated compounds while Cs-promotion decreases both; (2) the suppression of hydrogenation increases in the order: unpromoted < Li < K < Cs; (3) the rate of CH/sub 4/ formation decreases in the order: unpromoted > Li > K > Cs; and (4) the rate of CO conversion to hydrocarbons and oxygenates decreases in the order: Li > unpromoted > K > Cs. 35 references, 1 figure, 7 tables.
